使用说明 (SKILL.md)
Log Analyzer
Script
scripts/log-analyzer.sh — the single entry point for all analyses.
The script is self-contained, works on any Linux system with standard tools (grep, awk, sort, uniq), and handles both file and piped input.
Quick Start
Analyze /var/log/syslog with all checks:
bash scripts/log-analyzer.sh -f /var/log/syslog --all
Or pipe logs directly:
journalctl -u nginx --since "24 hours ago" | bash scripts/log-analyzer.sh --all
Options
| Option | Description |
|---|---|
-f \x3Cfile> |
Log file to analyze (use - for stdin) |
-p \x3Cpattern> |
Custom error pattern (default: error/i, fail/i, warn/i, critical/i, exception) |
-t \x3Chours> |
Time window in hours (default: 24) |
--errors |
Find top error messages and their frequency |
--time-analysis |
Group errors by time period (hourly/daily) |
--ips |
Analyze IP frequency from log entries |
--spikes |
Identify unusual patterns and spikes |
--all |
Run all analyses (default if no option given) |
--help |
Show this help message |
Analysis Modules
Error Patterns (--errors)
Scans for configured error patterns, groups and sorts by frequency, shows the top most common error messages.
Time-based Analysis (--time-analysis)
Groups errors into hourly and daily buckets to show when issues occur most frequently.
IP Frequency (--ips)
Extracts IPv4 addresses from log entries, counts occurrences, and shows the top sources.
Spike Detection (--spikes)
Compares error counts per time bucket against the average. Flags buckets that exceed 2x the average as potential anomalies.
Common Findings & Recommendations
- Repeated errors from the same source: Check application/service health; consider rate limiting or restart
- Time-based spikes: Correlate with cron jobs, deployments, or traffic patterns at the flagged times
- High-frequency IPs: Could indicate brute-force attempts, scrapers, or DDoS — consider firewall rules or fail2ban
- New error patterns appearing: Recent changes or deployments may have introduced regressions
- Sudden increase in warnings: Often precedes critical failures — investigate proactively
Notes
- Piped input reads from stdin; use
-f -explicitly when piping - For large log files (>100MB), consider reducing the time window with
-tor pre-filtering with grep - Time-based analysis expects standard syslog date formats (RFC 3164 or RFC 5424); custom formats may need adjustment
- IP detection uses a standard IPv4 regex — IPv6 is not currently supported
- Works without root for user-owned log files; system logs may require sudo
安全使用建议
This looks like a benign local log-analysis skill. Before using it, confirm the file path or piped command is the log source you intended, avoid sudo unless required, and remember that logs can include IP addresses, usernames, errors, or other operational details that may appear in the analysis output.
功能分析
Type: OpenClaw Skill
Name: laolaoqi-log-analyzer
Version: 1.0.0
The log-analyzer skill is a legitimate utility for parsing and summarizing server logs. The bash script (scripts/log-analyzer.sh) uses standard Unix tools like grep, awk, and sed to identify error patterns, calculate IP frequencies, and detect spikes without any evidence of malicious behavior, data exfiltration, or unauthorized access.
能力评估
Purpose & Capability
The described purpose—analyzing log files for errors, IP frequency, time patterns, and spikes—matches the documented shell script behavior.
Instruction Scope
The skill is meant to run a local shell script against user-selected files or stdin; users should only point it at logs they intend to analyze because logs can contain sensitive operational data.
Install Mechanism
There is no install spec, but the skill includes a shell script and depends on local Unix tools such as bash, grep, awk, sort, uniq, sed, wc, mktemp, and bc. This is purpose-aligned but not fully reflected in the registry requirements.
Credentials
The script performs local text processing and does not show network calls, external uploads, or unrelated system access in the provided artifacts.
Persistence & Privilege
The script creates a temporary file and removes it on exit; SKILL.md notes that system logs may require sudo, so users should avoid elevated access unless necessary.
如何使用
